Abstract

Abstract: In the era of big data, more and more users prefer messaging applications with end-to-end encryption to protect their privacy. However, if a hacker gets the password or encrypting key, it is possible to login into the account, or intercept the network packets and get the original messages. This paper introduces a new decentralized online messaging system that combines PGP and Diffie–Hellman key exchange and gives forward secrecy to end-to-end encrypted messaging. It is not possible for the hacker to decrypt the intercepted messages once the temporary session is ended, even if the hacker gets the PGP private keys.
